- REPEATIN'e-CLOCK.

SPECIFICATION forming part of Letters Patent No. 278,105, dated May 22, 1883.

Application tiled March 23, 1883.

To all whom 'it may concern: y

Be it known that I, WALTER D. DAvrEs, of the city of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in the Repetition Strike-Movements of Clocks, of which the following is a specification, reference being had to the accompanying drawings.

In what are known as repetition strikemovements of clocks the locking-piece which locks the striking-wheel is acted upon to unlock the said wheel for allowing the repetition of the strike to be produced by 'means of a push-pin. This push-pin commonly protrudes through a special opening in the clock-case, and has provided for it a special guide in the case. According to my invention the said push-pin works through the post which supports the bell; and my inventionv consists, principally, in the combination, with the locking device which locks the striking-wheel, and

with a hollow or partly hollow post which sup# ports the bell, of a push-pin working through and sustained by said post, and adapted to move the locking device out of the way of the locking-wheel.

The invention further consists in certain details of construction hereinafter described and claimed, and illustrated by the accompanying drawings.

Figure l in the drawings is a front view of' the striking part of a clock with my improvement applied, showing the case and the bell in section and the bell-post partly in section. Fig. 2 is a View at right angles to Fig. 1. Fig. 3 isa side view ot the push-pin. Fig. et is a face view of certain parts of the striking apparatus.

A is the frameot' the clock-case, to which the front plate, B, of the clock-movement is secured. This frame isrepresented as formed with a bracket or arm, A', to which is firmly secured the bell-supportin g post C. This post may, however, be secured to the frame or to the clock-case in any convenient manner.

D is the bell, secured on a shoulder on the upper part ofthe post C by a nut, a, litting a screw-thread on the post.

The striking mechanism employed in carrying out my invention may be of any suitable kind capable ot producing a repetition. That which I have represented is the well-known (No model.)

rack strikii 1gmoveinent, and only needs. description sufticientto enable themanner of applying my invention to beunderstood.

J is the hammer.

E is the strikingwhee1, furnished with the usual pin, b, for operating on the tail c ot' the hammer, and giving motion, in the usual way, to the locking-wheel F, and through it,in the usual manner, to the fly G. The locking-wheel F carries thelocking-piu d, which stops against the locking-piece H, as shown in Fig. 4, at all times but when the clock is striking or when the locking-piece has been pushed out of the way of the said pin preparatory to striking, as shown in Fig. 1, at which time the said pin is temporarily locked by the lifting and warning piece I.

K is the rack, operated upon in the usual way by the gathering-pallet e, and held up in the usual way by the stop-pin fon the locking-piece, as shown in Fig. 4, while the locking-wheel F is'locked.

L Z is the pushlpin for operating on the upper end of the lifting and warning piece I, to make the lower end of the latter push out the locking-piece H and unlock the locking-wheel, as shown in Fig. 1, in which view the pushpin is shown pushed in, the locking-piu d being temporarily caught by the spur g on the lifting and warning piece I, which will hold it till the pressure of the'tin ger is removed from the push-pin. The push-piu L might in some clocksbe a simple straight pin, the lower end of which,l protruding through the bottom of the .bell-post, would impinge on and act directly upon thelifting and warning piece; but in the example represented the said pin, in order that the part l, which impinges on and acts directly on the lifting and warning piece, may clear allthe wheel-work ofthe clock-movement, has the said part Z made in the forni oi" suitable place for operating the pushpin, and l locking device for the purpose of unlocking the simple provision of a hole through the bell-post as a guide for the pin obviates the need of a special guide and support for the pin.

The push-pin, instead of being made of a 'single piece of the form described, with the elbow part l integral with the straight part L, may be divided at l into two pieces, separately fitted to the post, the upper piece, above the point Z', always inlpinging on the lower piece at that point, and being kept from being forced too far out of the post by being provided with the shoulder Z below the cap-nut a of the hollow bellfpost.

l/Vhat I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, with the device forlocking the striking-Wheel of a clock, of a pushpin passing through or within the supportiu g- 'post of the bell, and adapted to act upon the the striking mechanism, substantially as herein described.

2. The combination, with the locking-wheel and the lockingpiece,y and with a hollow post which supports the bell, ot' a pin passing through or within said hollow post, for actul ating the lookin g-piece to produce the liberation of the locking-wheel, substantially as herein described.

3. The combination, with the locking-piece H, the lifting and warning piece I, the bell D, and its hollow post, of the pin L Z, passing through the said post and impinging upon the said piece I, substantially as herein described.
